Residents in southeast SA to 'take shelter' as out-of-control-fire burns in Sherwood

Fire crews have managed to bring the out of control blaze at Sherwood under control after it tore through South Australia's south-east.

A "wall of flames" ripped across more than 8000 hectares of bushland in the region near the Victorian border, threatening nearby towns of Keith and Bordertown.

The inferno put a Country Fire Service crew in danger as the blaze swept over them in their truck.

The crew were among more than 70 firefighters who battled the blaze at Sherwood, prompting the CFS to issue an emergency warning for local residents after it destroyed two farm buildings and threatened homes.

Assistant chief officer Daniel Austin said the crew followed standard procedures and reports from the area indicate they were unharmed.

"They engaged their normal burnover procedures, which they train for each summer and waited until the fire had passed through, checked their appliance and moved away," he said.

"The reports I have at this time is there was minimal damage to the appliance and there are no injuries.

At the height of the blaze an emergency warning was issued for the Sherwood, Brimbago, Lowan Vale, McCallum and Senior areas near the South Australian-Victorian border and locals were warned that it was no longer safe to leave.

A local farmer reported a "wall of flames" as the bushfire burned out of control.
